Yesterday, I traced the heavy line from the sender to the
oil temp gauge. I found at least 2 spots (one near the headers and another under the dash) where the heavy line is crimped with a radius of about 1/4". If it is mechanical in nature, then this is NOT good, resulting in a pessimistic reading. In general, my
oil temp never shows above 150*F on the gauge. Yet my water temp gauge is in the 175-185F range. To my mind, they should eventually be about equal.
I think I will order a new gauge. I do have a sandwich thermostatic adapter, which opens at about 180*F or so. My
oil cooler hoses are hot to the touch after a run so it is working.
That is what I mean by a pessimistic reading on the gauge. I do not look forward to working under the dash to disconnect and insert a new gauge. It is such a Pain in the Arse to work under there behind the dash. It appears to be a simple install though, albiet uncomfortable.
The real challange is in the routing of the line. Does anyone know aprox how long a line to order. SW has these in various lengths...
